A paper in Physics Letters B has raised the possibility that the Large Hadron Collider (LHC) could make a
discovery that would put its previous triumph with the Higgs Boson in the shade. The authors suggest it
could detect mini black holes. Such a finding would be a matter of huge significance on its own, but might
be an indication of even more important things.

Few ideas from theoretical physics capture the public imagination as much as the “many-worlds hypothesis,”
which proposes an infinite number of universes that differ from our own in ways large and small. The idea has
provided great fodder for science fiction writers and comedians. However, according to Professor Mir Faizal from
the University of Waterloo, "Normally, when people think of the multiverse, they think of the many-worlds
interpretation of quantum mechanics, where every possibility is actualized," he said to Phys.org. "This cannot
be tested and so it is philosophy and not science." Nonetheless, Faizal considers the test for a different
sort of parallel universes almost within our grasp.

“What we mean is real universes in extra dimensions,” says Faizal. “As gravity can flow out of our
universe into the extra dimensions, such a model can be tested by....................................
